Abstract

Novel polychloroprene sol-gel blends employing as crosslinking agents in the gel portion thereof a polymerizable monomer having three double bonds which will copolymerize with chloroprene and as chain-transfer agent in the sol of a sulfur containing compound including prior art mercaptans, dialkyl xanthogen disulfides and new polysulfides to produce vulcanizates having properties equal to or superior to prior sol-gel blends requiring the use of only dialkyl xanthogen disulfides as the sol chain-transfer agents.
